GUS-QS0B-03-1272-BB Description

The GUS-QS0B-03-1272-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 12.7KΩ resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it maintains stable performance across a wide operating range of -55°C to +125°C, making it suitable for environments with thermal fluctuations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads. Its gull-wing termination ensures reliable solder joints in automated PCB assembly processes.
